I'm trying to build a Modula-2 interface to a C-library an have hit
a snag.  Can anyone construct a suitable translation of:

    struct obj_name {
       int obj_type;
       union {
          int id;
          char *path;
       } obj_id;
    };


All my attempts are quite ugly and reqire introducing more extra
identifiers and syntax than I would like.
